IMPR'ovEn GASMACHINE.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom itmay concern.-

Beit known .thatrwe, ANDREW R. SPANG, and DANIEL F. SCHEAF, of Dayton, in the county of I `Montgomery, and in the State of'v Ohio, have invented certain'new and useful Improvements in Gas-Machines; and do hereby declare that the followingis a full, clear, and exact description thereof, reference 'being .had to the accompanying drawings, and to the letters" of reference marked thereon.

` Our invention is intended as an improvement on the gas-machine patented by Daniel F. Scheaf', J annary 7, 1868,; and consists in so arranging `the heating-` coil that it will receive its requisite supply of `fuel from the gasoline itself, instead of passing it through astove, as in the patent referred to.

In order to enable others skilled in the art to which `our inveutionappertains, tolnake and use the same, we

will now proceed to describe its construction and operation, referring `to the annexed drawings, which form a part of this specification, and in which- Figure 1 is a sid'eelevation, showing the machine itself in section Figure 2is a side view of thepipe and burner under the heating-coil; r

Eigure 3 is a plan view with the gasometer or cap removed; and, v i

'Figure 4 is a horizontal section, showing the interior arrangement of thelower part of the machine.

O represents the pipe, with a funnel at thetop, through which gasoline is introduced into the tank E. The gasoline passes out through the pipe A near the bottom of the 1nachine,.which 'pipe is provided with a branch-pipe and burner, B, so placed that the `burner will be'- directly under the coil of the pipe A.

part of the gasoline, while the balance is heated in the coil making the gas, which passes through the upper end of' the box A into the-chamber F, which is lled with sponge, or other suitable material, then through rpipe D into the gasometer, from gasometer back into the oil-tank, and then to the place where it is to be used.

By the arrangement of the pipe A, forming a coil .outside of the machine, and providing the lower part of said pipe with a branch-pipe and burner, B, it will be seen that the heatingcoil receives the requisite supply of fuel from the gasoline itself, thus man uf'acturing the gas whenever the burner is lighted.

We do not claim heating the fluid in a coil outside of the generator, so as to cause a circulation ofthe f lnid and the generation of gas, as this is described in the patent of Oakes Tirrell, of June 5, 1866.

Having thus fully described our invention,

What we claim as newfand desire to secure by Letters Patent, is-' y 1. So arranging the heating-coil of a gas-machine,

that it will receive its requisite supply of fuelfrom the heavier part of the gasoline,'substantially as herein set'forth.

2. yThe arrangement of the pipelA and branch-pipe and burner B, substantially as and for the purposes hereunto set our hands, this 1st day of Maroh, 1869.

AND. It. SPANG.
